Crawl puts the player in the role of a mental physician who has entered his patient’s mind in order to deal away with their traumas. Taking inspiration from traditional first-person dungeon crawling games of yesteryear, Crawl breathes new life into a classic genre by introducing a verb system and action-timing combat. Throughout the game the player will traverse incredible dream worlds, fight bizarre infections, and reunite memory fragments. Crawl is a student project and is in some ways heavily flawed; however, it is an impressive demonstration of how far the Game Maker engine can be stretched.
This is the source Game Maker project for Crawl. Totally open and what not; no credit required if you want to use it in your own project. I must apologize for the code being an abysmal mess, but sometimes in development, especially for a project like this, one just has to hack something together. If you make something cool with this, I would love to see it!
